Long-span steel roof trusses inside a stadium

Stadium Structure

Long-span roofs, grandstands and canopy frames.

Stadium roofs and grandstands need long spans with as little self-weight as possible. H-beams carry the primary frames, while welded square and round tubes build the trusses and canopy structures that give large venues their shape.

What the project needs

  • High strength-to-weight ratio for long spans
  • Consistent section dimensions for site assembly
  • Galvanized or painted finish for exposed members

Common standards: GB/T 11263, EN 10025-2, ASTM A6 / A500

Bridge Structure

Girders, deck plates, piers and reinforcement.

Bridges combine heavy plate for box and plate girders, rolled sections for secondary members and rebar for concrete decks and piers. Toughness at low temperature and full traceability to the mill certificate matter for every piece.

What the project needs

  • Medium and heavy plate with impact-tested grades
  • Mill Test Certificates traceable by heat number
  • Cut-to-size plate to reduce site work

Common standards: GB/T 714, EN 10025, ASTM A709

Embankment Structure

Quay walls, river banks, flood defences and piling.

Embankments, quay walls and flood defences use large-diameter spiral pipe as piles, heavy plate for retaining structures, and rebar and mesh for the concrete that holds them together.

What the project needs

  • Large-diameter pipe for piling
  • Anti-corrosion coatings for soil and water exposure
  • Long lengths delivered in project batches

Common standards: GB/T 9711, API 5L, EN 10219

Shipbuilding Structure

Hulls, decks, bulkheads and offshore platforms.

Hulls, decks and bulkheads are built from shipbuilding plate produced to classification-society rules, with angles and flat bars as stiffeners. Offshore platforms and port cranes use the same plate families.

What the project needs

  • Plate to CCS, ABS and other class rules
  • Good weldability and seawater corrosion resistance
  • Precise thickness tolerance

Common standards: CCS, ABS, DNV, LR class rules

Factory roofs covered with solar panels

Solar Structure

PV mounting rails, purlins and ground-mount frames.

Solar mounting systems need light, strong sections with long-lasting corrosion protection. Zinc-aluminum-magnesium coil and tube, C-sections and galvanized angles are the standard materials for rooftop and ground-mounted arrays.

What the project needs

  • ZAM or heavy zinc coating for 25-year outdoor service
  • Roll-formed C-sections and purlins
  • Pre-punched and cut-to-length parts

Common standards: EN 10346, JIS G3323, ASTM A1046

Greenhouse Structure

Light galvanized frames for agricultural greenhouses.

Agricultural greenhouses are framed in light galvanized round and square tube that stays rust-free in humid growing conditions, with C-sections for gutters and purlins.

What the project needs

  • Hot-dip or pre-galvanized tube for humid conditions
  • Light wall thickness to control cost
  • Bent and punched parts to drawing

Common standards: GB/T 3091, EN 10255, ASTM A53

Tunnel Structure

Steel arches, linings, rock support and pipe roofs.

Tunnels rely on I-beam arches and lattice girders for initial support, welded mesh and rebar for shotcrete and linings, and steel pipe for pipe-roof pre-support in weak ground.

What the project needs

  • I-beams bent to arch profiles
  • Welded mesh and rebar in project quantities
  • Steady supply matched to excavation progress

Common standards: GB/T 706, GB/T 1499.2, GB/T 1499.3

Building Structure

Steel frames, concrete reinforcement, roofing and cladding.

Commercial, industrial and residential buildings combine steel frames, reinforcement for concrete cores and slabs, and coated coil for roofing and wall cladding.

What the project needs

  • H-beams and columns for steel frames
  • Rebar and coiled rebar for concrete
  • Pre-painted and Galvalume coil for envelopes

Common standards: GB/T 11263, GB/T 1499.2, EN 10169
